Bella's , Er, Booty Call With Jordan!

The supermodel + the boy from Byron = hottest hook-up ever!

Who knew Bella Hadid was such a fan of the talent Down Under? The supermodel was snapped getting cosy in her underwear with Aussie model Jordan Barrett during a sexy snuggle sesh at her New York apartment on June 12.

And while most of us would be, er, bummed about getting sprung in the throes of passion, the way Bella was pressing her cheeks against the glass – after spotting the snappers! – seemed to suggest she didn’t give a damn!

“She clearly wanted people to watch,” a passerby says of the babe, who at one point was seen stroking topless Jordan’s face.

“She was climbing all over him and didn’t even bother putting on any clothes or closing the curtains.”

The lovebirds – who were first linked in April – then headed out to the balcony, where they posed for sexy selfies.
